"Relative age is the age of a rock layer (or the fossils it contains) compared to other layers." --VERSUS-- "Absolute age is the numeric age of a layer of rocks or fossils." other words - if they say absolute age, they KNOW what it is to a million years or so.Absolute age is more straight-forward and does not require any other objects for comparison.relative age (¡ärel¡¤əd¡¤iv ¡ä¨¡j) (geology) The geologic age of a fossil organism, rock, or geologic feature or event defined relative to other organisms, rocks, or features or events rather than in terms of years.However, this does not say anything about the absolute age of the layers.That is, scientists cannot tell exactly how old the layers are in years to the present date, only which is older than the other.If archaeologists find a site with layers in it, they can make assumptions about the relative age based on the composition of materials in each layer.
Relative age will require the comparison of two or more objects, whereas absolute age does not.
Continue Reading Relative age comes up often in various fields, such as archeology.
Techniques such as radioactive dating, including carbon dating, focus more on the absolute age of an object.
An example of this type of aging includes rocks in Canada that scientists identified as being hundreds of million years old.
